From asills at mcmaster.ca Fri Nov 15 10:36:34 2024 From: asills at mcmaster.ca (Alison Sills) Date: Fri, 15 Nov 2024 10:36:34 -0500 Subject: [MODEST] First announcement of the conference `Bridging scales: star clusters and their hosts from the Local to the high-z Universe' - Matera 1-5 September 2025 {External} In-Reply-To: <1d44c2ae-1c77-4089-a54b-a7a934736dfe@mcmaster.ca> References: <1d44c2ae-1c77-4089-a54b-a7a934736dfe@mcmaster.ca> Message-ID: <0ab11e28-b353-4736-a17a-baa048a68aac@mcmaster.ca> Dear all, We are happy to announce the international conference *Bridging scales: star clusters and their host galaxies from the Local to the high-z Universe* which will be held in *Matera (Italy) from the 1st to the 5th of September 2025.* * * Website:**https://sites.google.com/inaf.it/bridging-scales-in-matera-2025/ Contacts: bridgingscales2025 at gmail.com *Rationale* Observations of the local and high-z Universe confirm that star formation is an inherently clumpy and clustered process and, as a consequence, the physical properties of star clusters are expected to be intimately linked with those of their hosts. In particular, the long-lived massive star clusters can be used to trace galaxy assembly and the gas properties at the time of their formation, and they may be one of the primary sources of reionization of the Universe. This field is currently undergoing a revolutionizing phase. Large surveys carried out with ground and space based telescopes (such as Gaia, HST, Euclid, ALMA, ESO/VLT) have enabled unprecedented photometric and spectroscopic studies in the Local Universe and the JWST?s access to rest-frame optical wavelengths at z>3 along with the magnification power of gravitational lensing are opening a new era in the study of the star-forming modes well within the reionization epoch allowing us to directly probe star cluster formation and constrain unprecedented/unexpectedly dense stellar systems as possible sites of GC formation. The formation and evolution of star clusters is definitely a multi-physics and multi-scale problem, involving star formation and feedback, galaxy formation and evolution, N-body dynamics, stellar and binary evolution. As a consequence, the broad range of interconnected issues concerning the study of star clusters and their host galaxies can be addressed only with an interdisciplinary approach. In this exciting and rapidly changing context, we aim at bringing together observers and theorists from both the local and high-z Universe communities. The goal is to inspire discussions and exchange ideas about how to perform a transformative leap in the field, build a comprehensive picture of star cluster formation and evolution, explore the link between old massive, young star clusters and high-z proto-globular clusters, their connection to galaxy formation and their potential role in the reionization of the Universe. Focus will be given to how efficiently leverage available observations spanning different spatial, temporal and physical scales, along with those that will be soon on-line thanks to the several upcoming new giant facilities (such as E-ELT, Vera Rubin Telescope, Nancy Grace Roman Space Telescope, GMT), and the new generations of dynamical and cosmological hydro-dynamical simulations at spatial scales suitable to resolve stellar clusters. The *key scientific topics*?that will be covered at the conference are the following. * Local young clusters: insights on cluster formation and early evolution * Local globular clusters and globular cluster systems and their link with galaxy assembly and evolution * High-z observations of proto-clusters and dense stellar systems: their role in the early Universe * Cluster formation in the context of cosmological simulations * Next generation of observational facilities *SOC* Emanuele Dalessandro (INAF OAS; co-Chair) Alison Sills (McMaster University; co-Chair) Mario Cadelano (University of Bologna) Michela Mapelli (Heidelberg University) Florent Renaud (Observatoire Astronomique de Strasbourg) Eros Vanzella (INAF OAS) Enrico Vesperini (Indiana University) -- Alison Sills Professor, Physics & Astronomy -------------- next part -------------- An HTML attachment was scrubbed...
